The customer, Stanbic Bank of Kenya, is a pivotal banking division of Standard Bank group, a leading financial institution with a strong presence across Africa and South Sudan.

Stanbic Bank is committed to delivering secure, innovative, and customer-centric banking experiences to customers in the region. To stay ahead of evolving market needs and regulatory requirements, Stanbic Bank sought to modernize its core banking system with a next-generation solution from Temenos.

Challenge

Stanbic’s existing core banking platform was reaching the limits of scalability and performance. The bank faced challenges in:

  • Managing legacy infrastructure and multiple integrations 
  • Ensuring compliance and data security 
  • Supporting the agility required for new digital products 
  • Improving system performance and transaction turnaround times 

To future-proof operations and strengthen customer engagement, Stanbic decided to upgrade from T24 R17 (TAFC framework on AIX) to the latest Temenos Transact T24-R23 (TAFJ framework on Linux)—a major transformation demanding deep expertise and precision execution.

“Technology and innovation are central to our business strategy. This upgrade strengthens our ability to provide secure, efficient, and cutting-edge banking solutions to our clients both locally and globally. We appreciate Orion’s expertise and commitment to excellence in delivering this successful transformation.” 

— Dr. Joshua Oigara, Chief Executive, Stanbic Bank, Kenya  

Solution

Orion Innovation, a globally certified and trusted Temenos partner, was selected to lead the transformation due to its proven track record in core banking upgrades and complex system migrations.

FAQs

Your questions,

A core banking transformation is the process of upgrading or replacing a bank’s core banking platform to improve performance, scalability, security, and digital capabilities. It typically includes modernizing infrastructure, applications, integrations, and testing so banks can support new services while maintaining day-to-day operations.

Banks upgrade their core banking systems to improve operational efficiency, support digital banking services, meet regulatory requirements, and address limitations of legacy platforms. Modern core banking platforms also help institutions process transactions faster, scale more easily, and introduce new products with less complexity.

A core banking upgrade minimizes disruption through phased planning, detailed testing, controlled migrations, and structured deployment. Organizations often use automation, regression testing, and staged validation to identify issues before go-live, helping maintain business continuity and reduce operational risk.

Modernizing a legacy core banking platform improves system performance, operational efficiency, and long-term scalability. It can also strengthen security, simplify maintenance, reduce manual processes, and enable banks to launch digital products faster while supporting future business growth.

System integrations are critical because core banking platforms exchange data with payment systems, customer channels, regulatory applications, and other enterprise systems. Successful integration planning helps maintain uninterrupted business processes and ensures consistent data across the banking ecosystem.

Automated testing improves the quality and reliability of a banking platform upgrade by validating system functionality before deployment. It reduces manual testing effort, identifies defects earlier, accelerates project delivery, and lowers the risk of production issues during and after go-live.

A bank should consider modernization when legacy systems limit scalability, slow product launches, increase maintenance costs, create integration challenges, or make regulatory compliance more difficult. Modernization also becomes important when customer expectations require faster, more digital banking experiences.

Organizations should evaluate their existing technology landscape, integration dependencies, regulatory requirements, migration complexity, testing strategy, and business objectives before beginning a core banking transformation. A comprehensive assessment helps prioritize risks, define the implementation roadmap, and support a smoother transition.
